MFA that gets out of your way
Your browser detects the site. Your phone gets a tap. The code fills in.
FactorCat connects your browser, phone, and authenticator tokens into a seamless approve-and-autofill flow.
"I was sick of the old model. Pick up my phone, scroll through poorly-named accounts, find the 5 that all match the same site, memorize a code before the timer runs out, switch to my browser, and key it in. Every. Single. Time."
"Now I click a field and my phone buzzes. One tap and I'm in."
Push to approve
Your browser extension detects the MFA field. Your phone gets a push. Tap approve and the code fills in automatically. No switching apps. No copying digits. No racing the timer.
Security that matches the risk
Your bank gets Locked Vault and one-tap approval. Chipotle gets Cloud Vault and zero-tap auto-fill. Both free — you decide what each account deserves.
Not a password manager
On purpose. Your passwords stay in 1Password or Bitwarden. FactorCat handles only your second factors. No single point of failure.
